FE (→EE, GE1 (→GE2) has a cautionary 
before a before the 2nd chord in the L.H. It is a remaining element of the original notation of the 1st chord, in which there was an a
instead of g
(traces of a corresponding proofreading are clearly visible in FE). The accidental, unjustified in the final version, was removed in GE3. In GE1 (→GE2), cautionary naturals before c and c1, as well as before the c2 semiquaver, were added before that chord. We include all of them in the main text. A natural before c was added also in EE2 (→EE3), whereas in GE3 all accidentals before the 2nd chord were removed; only the before c2 was left.
